THEMES OF THE TOP 1000 ANIME IN 2023

Rationale:

Japanese animation, also known as Anime, has gained immense popularity over the years. As I grew up watching anime, the topic of which Genre or Theme was more interesting always sparked a debate between me and my friends. And thus, for my final project for PSY6422, I will try to visualise common recurring themes in the top 1000 highly rated anime of the year 2023 on My Anime List.

Action, adventure, comedy, drama, romance, fantasy, sci-fi, and many more genres are covered in anime. Better recommendation systems can be created by having a better understanding of which genres perform better. The reason why I choose themes over genre is because one anime could have multiple themes thus making our criteria more inclusive and relatively comprehensive.

The data will be visualised in a bar graph as it is approparite to convery the information I want to visualise (Ranking the count of themes & sources). I am using Plotly to create an interactive version of my plot as the graph as multiple columns which can be hard to follow & the reader might benefit from the interactive nature of the graph by simply hovering over the column to see its description i.e, The name of the theme and the count.

Question I aim to visualise:

  • The top animes had which themes?

Source of the Dataset :

The dataset was acquired from Md Kazi Sajiduddin on kaggle. It was created around July 2023. Jikan Application Programming Interface (4.0.0) was used to extract the anime dataset via the My Anime list. The original dataset retrived anime-related data, inclduing the original title, the english title, Demographics, Start season, Airing date,Format, Studios, Synopsis, Production house, The User ID and the scores given by the users. MyAnimeList.

What is My Anime List?

Frequently shortened as MAL, MyAnimeList is a volunteer-run website that provides social networking and social cataloging services for fans of anime and manga. Users of the website can score and arrange anime and manga using a system similar to a list. It offers a comprehensive database on anime and manga and makes it easier to find users with similar interests.

What will my project include?

The data included 24,985 anime titles that were rated by users on My Anime List. The original dataset had a plethora of information including The original title, english title, Demographics, Start season, Airing date,Format, Studios, Synopsis, Production house, The User ID and the scores given by the users. For my project, I will examine the top 1000 anime titles in the dataset to identify recurring themes. Additionally, I will also visualise if the Source of the anime, taking a look at if the anime was derived from a Manga (Comic book), Web novel, Light novel or was an original creation and so on. Thus, I make sure only these columns are retrived from the rawdata.

Folders in my project:

The /Data consists of the raw data acquired from kaggle, /figures consist of the Plots generated in the project and /images consist of the image used in the project.

Insights:

2023 saw a lot of successful anime releases in a variety of genres. However, a clear trend became apparent: audiences were drawn to stories set in schools. Other themes that did well were Adult Cast, Historical, Psychological, Super Power, Mythology, Military, and Isekai. One prominent genre of anime was shounen, which catered to young boys. The predominance of themes like school,action and adventure, which are typically popular with this demographic, may be explained by this focus on a male audience. Seinen, an anime series targeted at adult men, is among the top demographics, though, indicating a more complex picture. Seinen anime often explores mature themes like psychology and complex character development, which could explain why these themes were also highly rated in 2023. This implies that when deeper themes are presented in an engaging manner, viewers—even younger ones who appreciate Shounen—may be drawn to them.

Closing remarks:

I was able to pick up a new skill at my own pace with this module. I can say have relatively become capable of using R Studio and Github over time. I also used this chance to investigate various packages and themes that might improve my project in some way. I also explored managing project environments with renv to ensure the required packages are installed appropraitely over different devices. If I had more time to work on the project, I would have loved to plot all of the variables based on various criteria (for example, contrasting highly rated versus low rated anime titles) to have a comprehensive understanding of criteria that make an anime series highly rated. The following plots were based on the top 1000 titles, for a more comprehensive analysis, data of all the titles can be visualised by future projects.
